WALTER E. COLEMAN, OF NEWDORF, NEW YORK, ASSIGNOR TO THE COLE- MANMANUFACTURING COMPANY, CORPORATION OF NEW YORK.

AUTOMATIC FAN.

SPECIFICATION forming part of Letters Patent No. 708,622, datedSeptember 9, 1902. l Application filed December 10, 1901. Serial No.85,374. (No model.)

ing is a specification sufficientto enable oth-' ers skilled in theart'to which the invention appertains to make and use the same.

My invention relates to means for controlling and directing air-currentsgenerated by fans; and it consists in the special construction of partshereinafter described and claimed specifically.

' In the accompanying drawings, Figure 1 is a side elevation of thedevice; Fig. 2, a sectional elevation upon plane of line 2 2, Fig. 1;Fig. 3, a rear elevation; Fig. 4, a top view showing a portion brokenaway.

From the base B extend upward the arms 1), between which is pivotallysuspended the ring O upon screws 0, by means of .which it may be rigidlyheld at any inclination desired. The electric motor M is pivotallysupported within the ring O by vertical trunnions m in such manner as toallow it to turn freely in the plane of the axes of its power-shaft m,upon the rear end of which is the worm-screw m located between thebearings m rigidly secured to the motor.

Supported in bearings m m and also rigidly secured to the motor is theupright shaft D, carrying the pinion d, which engages with saidscrew-worm, the upper end of said shaft D being formed with a crank-armd.

Rigidly attached to or forming a part of the ring 0 is therearwardly-projecting arm 0', to which is fulcrumed one end of the levere. The opposite endof said lever is pivotally connected to the wrest-pinof the crankarm d. The wrest-pin of the crank -arm d also engagespivotally with the rear end Z of the rocking lever L, the fulcrum Z ofwhich is attached rigidly to the motor M and the outer or forward end ofwhich, 1", engages with a wrest-pin 9, attached to one of the vibratorydeflectors H, which are connected together by a rod h or equivalentmeans, substantially as set forth in my concurrent application, SerialNo. 67,952, filed July 12, 1901. The end Z of the lever L is formed witha longitudinal slot 1 to admit of the play of the wrestpin g, and inlike manner this lever is formed with the longitudinal slot Z adjoiningthe fulcrum Z. r

F is the fan of ordinary construction, surrounding which is the guard G,in which are pivotally supported the oscillating deflectors H.

The operation is as follows: The rotation of the motor-shaft m impartsmotion slowly through the worm m and pinion d to the upright shaft D,thereby rotating the crank 01. As a result of the connection of thewrest-pin and the crank with the lever e the latter,owing to its pivotalconnection with the rigid arm 0', oscillates the motor M upon itstrunnions m, thereby causing the fan and guard to describe the arc of acircle alternately in either direction, the extent of this reciprocatingmotion being governed by the throw of the crank d. Simultaneously withthe above action the rocking of the lever L upon its fulcrum Z,

owing to the rotation of'the crank (1, causes the other end Z of saidrock-lever to vibrate the deflectors H substantially in the manner andfor the purpose set forth in my said concurrent application hereinbeforereferred to.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination of a fan F, an electrical motor M, pivotallysupported in the ring 0, said ring 0, pivotally supported between thearms I), b, upon the base B, and formed with the rigid arm 0, thelever-arm e, pivot- 85 ally connected to said rigid arm 0, and to thecrank 01, said crank d, shaft D, and pinion d, and the motor-shaft m,formed with the worm-screw m engaging with said pinion d, for thepurpose and substantiallyin the man- 0 nor set forth.

2. The combination of a fan F, an electrical motor M, pivotallysupported in the ring 0, said ring 0, pivotally supported between thearms Z), I), upon the base B, and formed and the deflectors H, togetherwith said dewith the rigid arm 0', the lever-arm e, pivotflectol's,arranged and operated substantially ally connected to said rigid arm 0',and to the crank 01, said crank d, shaft D, and pinion (Z, and themotor-shaft m, formed with the l Witnesses:

in the manner set forth.
